On Tuesday, the board of market regulator Sebi cleared the proposal to cap the maximum total expense ratio (TER)-the fee that mutual funds collect from investors every year to manage their money-for closed ended equity schemes to 1.25 per cent and other than equity schemes to 1 per cent.

The maximum TER for open ended equity schemes has been capped at 2.25 per cent.

TER is a percentage of a scheme's corpus that a mutual fund house charges towards expenses, including administrative and management.

The expense ratio has been capped according to the assets under management (AUMs) of the mutual funds. For schemes with AUMs up to Rs 500 crore, 2.25% will be charged as expense ratio every year. For the next Rs 500-750 crore, it will be 2 per cent. Between Rs 750 crore and Rs 2,000 crore, the fee will be 1.75 per cent. For Rs 2,000-5,000 crore, it will be 1.6 per cent and large equity mutual funds with assets above Rs 50,000 crore will be able to charge just 1.05 per cent.

Morningstar India in a note said, "With increasing fund sizes, the quantum of reduction in TER increases. For instance, this move will result in a reduction of 9bps in the TER of a fund with an AUM of Rs 5,000 crore, but a fund with an AUM of Rs 20,000 crore will witness a reduction of TER to the tune of 28 bps. This is exactly what SEBI is trying to achieve, to pass on the economies of scale of larger funds to investors."
